Notes
1. OUTPECL, OUTQPECL, OUTCML, OUTQCML, LOS and LOSQ outputs are left unconnected. OUTPECL and
OUTQPECL outputs are active.
2. OUTPECL and OUTQPECL outputs are terminated with 50 Ω to VT. VT is an external termination voltage for PECL
outputs and is 2 V below the supply voltage. OUTCML, OUTQCML, LOS and LOSQ outputs are left unconnected.
3. OUTCML and OUTQCML outputs are terminated with 50 Ω to VCCD; CML outputs are active. OUTPECL,
OUTQPECL, LOS and LOSQ outputs are left unconnected.
4. The bandwidth is set to 120 MHz by default. It can be varied between 90 and 150 MHz by adjusting the voltage at
pin BWC.
5. All In(tot) measurements were made with an input capacitance of Ci = 1.2 pF. This was comprised of 0.7 pF for the
photodiode itself, with 0.3 pF allowed for the PCB layout and 0.2 pF intrinsic to the package.
6. PSRR is defined as the ratio of the equivalent current change at the input (∆IIPhoto) to a change in supply voltage:
PSRR = ∆---∆--I--IV-P----hC--o-C--t--o-
For example, a 4 mV disturbance on VCCat 10 MHz will typically generate the equivalent of 2 nA extra photodiode
current.
